Does anyone know where to find the ruby qwt bindings?
According to RubyForge: Korundum/QtRuby - Ruby-KDE/Qt bindings: help, this should be part of the korundum/qt or qt4-qtruby, which I think are included in the ruby-kde4 package.
The qwt.rb and qwt.so files referenced in the link are nowhere to be found in either ruby-kde4 or the qt4-qtruby-2.1.0 source.
